“According to Pentagon data from fiscal 2015, the last time the Defense Department did a full inventory, the military spends at least $437 million a year on musicians, their instruments, special uniforms, travel and related costs. That marks a steady rise from previous years, even as the Pentagon insists the services have cut a sizable number of musical troupes. By some official estimates, it’s now spending $100 million more a year than in 2011.”
